Abstract
With the increased usage of the spectrophotometer in industrial analytical laboratories, it is essential that all potentialities of the instrument be examined. Employing the spectrophotometer for the observation of titrimetric endpoints opens up a relatively new field, which to an experienced analyst offers new and rapid procedures for previously tedious analyses. However, the spectrophotometer is a relatively expensive instrument, therefore, in part, it is the purpose of this paper to adapt some previously accomplished titrations to a less expensive instrument such as the Bausch & Lomb Spectronic 20 Colorimeter. The chelating agent, ethylenediaminetetraacetic acid, commonly called Versene, has already been used by other authors in such titration of many metals. In this paper, an attempt has been made to extend this range somewhat to include the titration of cobalt, and the titration of the copper ammonia complex which is present in alkaline copper solutions. Finally, the common method used for the determination of magnesium by precipitation with 8-hydroxy quinoline has been shortened and simplified by the use of the titration technique.
